徐深气田火山岩储层类型与主控因素研究

本文在对岩心资料、录井资料、常规测井及成像测井资料综合研究的基础上,对徐深气田火山岩储层类型进行了研究,说明火山岩相、不整合面和构造裂缝是影响火山岩储层最重要因素。有利火山岩相带和不整合面结合是形成层状优质储层最关键条件,有利火山岩相带顺序是:近源蒸汽涌流相、溢流相顶部和底部、热火山碎屑流、粗粒空落相、远源涌流相和细粒空落相。在离不整合面井段近处,溶蚀作用较强,容易形成优质储层。在离不整合面或喷发间歇面较远处,高角度一斜交构造裂缝是形成有效储层的必要条件。

RESEARCH OF THE VOLCANIC ROCK RESERVOIR TYPES AND MAIN CONTROL FACTORS IN XUSHEN GAS FIELD

Based on synthetic study of core,mud logging,conventional logging and imaging well logging data,the volcanic rock reservoir types in Xushen gas field are researched.It is showed that volcanic rock facies,unconformity surface and tectonic fissures are the most important factors which affect volcanic rock reservoirs.Combination of favorable volcanic rock facies zone and unconformity surface is the essential condition to form a good stratiform reservoir.The sequence of favorable volcanic rock facies zone from ...
